Poker players think that one night is pretty much like the others. If u searched their souls, they swear that they could play nearly as well tired or sick as theye could any other time. This is srious mistake.Players would do well to examine themselves carefully before every poker game. Occasionally they should place themselves on an injury list and declare themselves ineligible.
